FaradaIC and the EIC Accelerator: An Oxygen Sensor on a Chip

FaradaIC Sensors, a Berlin company led by CEO Ryan Guterman, makes electrochemical gas sensors on microchips, replacing the liquid electrolytes in conventional sensors with solid-state materials. Its EIC project promised "the first miniaturised electrochemical O2 gas sensor" for breathing devices, fitness, medical uses and the hydrogen economy, and aimed to take the technology from TRL 6 to TRL 8 with patents, pilot manufacturing and field tests with pilot customers, according to CORDIS.

The European Innovation Council granted €2,455,250 towards a €3.51 million project from March 2023 to August 2025. The final report says FaradaIC screened "over 100 innovative gas sensing materials and formulations", built three generations of microsensors and reached "the full validation and demonstration of our miniaturized O2 gas sensor". It targets a price of "10-20 cents" per sensor in mass production. In April 2025 it raised a €4.5 million seed round led by JOIN Capital, with the European Innovation Council among the investors, to bring its first oxygen sensors to market and expand manufacturing.

Where FaradaIC Stands Now

FaradaIC's website describes Faraday-Ox as the "world's first oxygen sensor on a chip", a factory-calibrated module with digital output, and invites customers to order an evaluation kit. It targets food packaging and supply chains, medical and biotech devices, and semiconductor equipment. Register records show a capital increase in February 2025, patents on a gas sensor and a lacquer mixture, and new trademarks in 2024 and 2026, according to North Data.

The Technology: Electrochemistry on a Wafer

Conventional electrochemical gas sensors are calibrated one by one, the report says, which adds cost. FaradaIC builds its sensors on wafers using proprietary materials, allowing automated calibration at wafer scale, and uses microelectrodes to keep power use low. The report describes a target of a 1x1 mm analog sensor; the product on sale is a 2x2 mm module with digital output. The company calls the approach MECS technology.

What the EIC Project Promised, and What CORDIS Shows

The project promised to reach TRL 8 through patents, pilot manufacturing and field tests with pilot customers. The final report documents materials screening, a patent filing, in-house gas testing rigs, a calibration procedure and a validated oxygen sensor, and names logistics as a new market. It does not mention pilot manufacturing, field tests or any customer. Of the €2.46 million grant, €669,375 went to FaradaIC's Serbian affiliate. CORDIS lists the project as closed.

The Money

The seed round's other backers were Forma Prime, elev8.vc, Tiburon, Frontures, Atlantis Ventures and angel investors. FaradaIC's registered share capital rose from €28,874 in April 2024 to €44,984 in February 2025. Its accounts and revenue are not publicly summarised, and the EIC's share of the seed round was not disclosed.

What Cannot Be Checked

Why Europe Should Care

Gas sensors small and cheap enough for wearables and packaging would open new markets, and FaradaIC wants to make them with standard semiconductor processes. The EIC funded that work and then invested. The public evidence of production and customers is thin.
